Application filed September 12, 1925. Serial No. 56,097.' I A Thisinvention relates generally to the manufacture of gems known ascabochons and more particularly to the application thereof for variouspurposes.

The subject matter of this invention is closely related to the inventiondescribed in my co-pending application Ser. No. 56,098, filed Sept. 12,1925.

\ For a full understanding of the invention and characteristic featuresthereof, reference is made to the accompanying drawings in which- Fig. 1is a plan view of a plate carrying a plurality of cabochons arrangedsingly and in p Fig. 2 is an elevation of a part thereof, partly insection;

Figs. 3 and 4 are side elevation and. end view, respectively, of aortion of the plate carrying a group ofca ochons, as severed from theplate and mounted on a pin;

Fig. 5 is a plan view of another portion of a plate carrying anothergroup of cabochons, severed from the plate; and

Fig. 6 is a plan view of a modification of the form. shown in Fig. 5.

This invention is based on the discovery more fully described in my saidco-pendmg application, that when a body, as for instance a plate, havinga perforation is pressed upon a body of molten vitreous material, theupper surface of the material assumes a definite curvature. Thus whenthe perforation is circular, the upper surface 1S spherical. The curvedcabochon surface is so uniforml smooth that even the best and most careul polish couldnot improve it.

Since a natural polish is thus obtained as the result of the process ofproducin the cabochons, the latter may be forme and mounted by one andthe same 0 ration. Advantage may be taken of this unique feature in manyways and for numerous purposes. K

I therefore wish to emphasize that the drawings are intended merely asgenerally illustrative and suggestive of the almost unlimited scope ofapplication of the invention.

In Figs. 1 and 2 I have shown a plate 1 of relatively-small thicknessand generallyof the order of stock used for mounting gems and preciousstones. This plate, which may be called a stencil plate is shown asperforated and carryin 4 groups a, b, 0, and d of cabochon gems. roup arepresents a plurality of typical cabochons 10. Group b represents aplurality of oval cabochons 11. Group 0 indicates a group composed of aplurality of different sized cabochons 12,

13 and 14 representing an ornamental unit. Gp-oup d indicates arelatively large number 0 cabochons 15 defining the letter A.

The common characteristic feature is a slight bevel or flaring 2 of theperforations at the lower side of the plate and preferably also asimilar flaring 3 at the'upper end of the perforations; When moltenglass, or V i vitreous material in general, is pressed through theperforations as for instance by pressing the plate 1 upon a. body ofmolten glass, the glass as it issues from-the, perforationsexpandsslightly and thus after coolmg cannot be removed in a downwarddirection. At the same time the molten glass fills the flaring portion 2so that after coolmg a secure anchor is also provided against motion inthe other directon. After the cabochons have been formed, the excessglass at the bottom is removed as by grinding and then the single gems,groups or units are cut from the plate with enough of the metal toprovide a mounting.

Thus, as indicated group 0 is shown as cut out from the plate 111 theform, of a disk 4 and then mounted upon a pin 5 forming a stick in. Asindicated in Fig 5, group (i may e cut out to serve as an ornamentalsymbol.

As indicated in Fig.6, the letter A may be formed by long cabochonsinstead of a group of circular forms. The elongated perforations-6actthe same as other erforations. The cabochons produced there y areuniforml rounded and form in substance semicylinders with the exceptionthat the ends are also rounded. v

The form of the gem depends generally on the outline of the perforation.The curvature of the upper surface adapts itself to the differentconditions.

In the foregoing I have restricted myself to the illustration of groupsformed by a'single any desired plan and profile. When per-- forationsare so close to each other that the molten material issuing at the topcoalesces or flows together, a single surface is produced exhibiting toa greater or lesser degree the characteristics of the individual formsas they would be produced separately from each other, but these formsare modified more or less by the degree of coalescence permitted. Oneillustration of this is the form shown in Fig. 6. The elongatedperforations are in effect a large number of circular perforations injuxtaposition and so overlapping each other as to form two straight sideWalls. If the overlapping were such as to produce scalloped side walls,the cabochon produced would include a plurality of mainly sphericalbodies interconnected by webs the Width and heights of which is afunction of the degree of overlap. There is, in fact, no limit inrespect to the formation of modified cabochon bodies. There is not ageometrical configuration that may not be simulated. Flowers and animalsmay be imitated more or less ornamentally depending on the skill andexperience of the designing artist. It would be futile within the scopeof this specification to even attempt to give illustrations of thevarious forms that may be created by the method described.

It is needless to say that the plate need not be plane or that theflaring of the openings need not be produced by beveling orcounterboring. The perforations may be produced by punching dies or infact in any well known manner. The recesses for producing the anchoringeffect may be rovided by bending, indenting, pressing t e plate or stockupon which the mounting is to take place.

Aside from the general utility of the invention in respect to theproduction of gems and ornamental designs proper, as above referred to,there is another field of application which I consider of greatimportance. The invention is particularly applicable to the formation ofsigns of all descriptions. Thus any name word or phrase may be composedof caboc ions, as suggested in Fig. 5. The cabochons may be of any coloror of different colors. In the day time, the signs are visible by lightreflections,.while provisions may be made to make them conspicuouslyvisible, at night by transmission of light through them. The art ofillumination is widely understood and appreciated and has proceeded tosuch degrees of specialized skill bordering almost on the realm ofmagic, that it would be superfluous to particularly indicate some of themany devious ways by which the artistic effect of signs made inaccordance with my invention may be conspicuously brought out.

Also inthis respect there is no limit to the combinations of words,signs, symbols and emblems that may be produced as the result ofcreative imagination.

I claim:

1. An ornamental structure of the character described, comprising aplate having substantially plane surfaces and an opening extending fromone plane surface to the other, and a body of vitreous material in saidopening, having portions preventing removal of the body in eitherdirection, one end portion presenting a symmetrically rounded surfacehaving the characteristics of a highly polished cabochon surface.

. 2. An ornamental structure of the character described, comprising aplate having substantially plane surfaces and an opening extending fromone plane surface to the other, the opening having a lateral enlargementof smaller axial extent than the thickness of the plate, and a body ofvitreous material in said opening having a laterally enlarged portioncorresponding to and filling the enlarged part of the opening, one endportion'of the said body presenting a symmetrically rounded surfacehaving the characteristics of a highly polished cabochon surface.

3. An ornamental structure of the charac ter described, comprising aplate having substantially plane surfaces and an opening extending fromone plane surface to the other, the opening having an enlargementadjacent to one surface, and a body of vitreous material in saidopening, having at one end an enlargement corresponding to and fillingthe EDWARD J.
